While I do not currently have tests to detail for you I will say that greater than 75% or our robot this year was created on the Velox router. Every single custom gearbox was made with it, the holes are not 100% perfectly round but are unlikely to with any router so we post ream all the bearing holes. Over 20 gearbox plates easy. Any tolerance issues we have had with it have been almost always user error and not the machine. We also made chain sprockets that if they are even off by a thou are terrible at meshing, worked fine every time(something the Haas vertical mill I have at work hasn't lived up to even).

As a side note, while I was picking ours up at their shop they told me that some clients had even managed to pull off machining stainless steel. That is nuts that they managed to do that with any router.
What are your typical cut parameters in aluminum? What size tool, speeds and feeds, width, depth? Im very curious now.
